cool Exhaust wrap on extractors?

Has any one put that heat shield wrap on their extractors before. I just read a autospeed article about this and it sounds cool?

Exhaust Wrap is woven from the finest insulating materials available, and can withstand temperatures in excess of 600 degrees Celsius. When wrapped around engine exhaust pipes, the High Energy Wrap can reduce under bonnet temperatures by as much as 80%, preventing heat related damage and helping to increase horsepower by reducing intake temperatures. High Energy Exhaust Wrap keeps the exhaust heat inside your exhaust pipes to maintain exhaust gas velocity, increasing combustion chamber scavenging and therefore horsepower.

Re: Exhaust wrap on extractors?

I've heard that it's good stuff, but can rust out your exhaust system quicker.

Any idea on price?

Re: Exhaust wrap on extractors?

I have read that they can cause the pipes to become brittle if too many layers are put on, is this true? It costs about $5 a metre i think, probably need about 3 metres to cover a set of extractors?

Re: Exhaust wrap on extractors?

I was told not to use it coz the pipes get too hot and crack. which sounds about right

Put a metal shield in if u want to lower ambient temp in the bay.. well thats what i was told to do. Its not a must, so mine is still unsheilded :)

Re: Exhaust wrap on extractors?

Like everything else in this world they have good and bad points.

After 8 years as fire marshall at the summernats I can tell you they will hold oil, if you have a leak (and any other fluid that leaks onto them). There have been more than a few engine bay fires attributable to engine/trans/steering lubricants that spewed onto the header tape.

The stuff does it's job, as far as cooling is concerned. However, unless you can justify the cost, spend the money elsewhere.

Re: Exhaust wrap on extractors?

The stuff destroys the extractors becauser of the heat build up,better option is ceramic coated.
